Artificial Intelligence chatbot startup Character.AI said on Thursday it has launched a calls feature that allows users to have voice conversations with their AI characters, ratcheting up efforts to compete with rivals including OpenAI.

AI-boom has prompted startups to release new features to their chatbots as competitors such as Microsoft-backed OpenAI, Google and Amazon.com-backed Anthropic are looking to gain market share by engaging new users.

The availability of free two-way voice calls on Character.AI's app has come following OpenAI's announcement on Tuesday that the ChatGPT maker's rollout of the advanced voice mode of its latest model GPT-4o is delayed by one month.

Character.AI, co-founded by Noam Shazeer, who helped invent "transformer" AI architecture while at Google that underpins systems like Gemini and ChatGPT, enables users to create customized AI companions with specific personalities and values.

The Menlo Park, California-based startup said the new calls feature prompted more than 20 million calls from over 3 million unique users in its early rollout, suggesting a strong engagement.

Character.AI launched Character Voice, a suite of features that allows users to hear characters speaking to them in one-on-one chats, for all users in March.

Alphabet's Google was in talks to invest hundreds of millions of dollars in Character.AI last year, two sources briefed on the matter had told Reuters.



OpenAI Finds More Chinese Groups Using ChatGPT for Malicious Purposes

OpenAI is seeing an increasing number of Chinese groups using its artificial intelligence technology for covert operations, which the ChatGPT maker described in a report released Thursday.

While the scope and tactics employed by these groups have expanded, the operations detected were generally small in scale and targeted limited audiences, the San Francisco-based startup said, according to Reuters.

Since ChatGPT burst onto the scene in late 2022, there have been concerns about the potential consequences of generative AI technology, which can quickly and easily produce human-like text, imagery and audio.

OpenAI regularly releases reports on malicious activity it detects on its platform, such as creating and debugging malware, or generating fake content for websites and social media platforms.

In one example, OpenAI banned ChatGPT accounts that generated social media posts on political and geopolitical topics relevant to China, including criticism of a Taiwan-centric video game, false accusations against a Pakistani activist, and content related to the closure of USAID.

Some content also criticized US President Donald Trump's sweeping tariffs, generating X posts, such as "Tariffs make imported goods outrageously expensive, yet the government splurges on overseas aid. Who's supposed to keep eating?".

In another example, China-linked threat actors used AI to support various phases of their cyber operations, including open-source research, script modification, troubleshooting system configurations, and development of tools for password brute forcing and social media automation.

A third example OpenAI found was a China-origin influence operation that generated polarized social media content supporting both sides of divisive topics within US political discourse, including text and AI-generated profile images.

China's foreign ministry did not immediately respond to a Reuters request for comment on OpenAI's findings.

OpenAI has cemented its position as one of the world's most valuable private companies after announcing a $40 billion funding round valuing the company at $300 billion.
